Venlafaxine Side Effects

Venlafaxine, popularly known as Effexor, is a commonly prescribed anti depressant drug, used to treat depression in adults. It has been proved time and again that Venlafaxine is a superior drug over many other anti depressants like Prolac and Zoloft. In fact higher doses of this drug have almost cured symptoms of depression in patients. It is medically also a better tolerated drug in most individuals than many other depression relieving drugs, hence its use is widespread in most countries. It is one of the most commonly prescribed drug in the United States with a record of around 17.2 million prescriptions in a year. However, Venlafaxine side effects are many and difficult to deal with.

The first reason that this is only an adult drug is simply because of one of the biggest Venlafaxine side effect. According to this, a person consuming this drug shows greater tendency of self harm or suicides. Hence this can not be prescribed to either children or adolescents at all. Preferably patients under treatment of Venlafaxine need to be under medical surveillance. In case if that is not possible, then family guidance and constant watch is important. In other cases, patients already suffering from glaucoma should not have Venlafaxine since it all the more increases internal eye pressure. Also, pregnant ladies should avoid this drug as much as possible since these are proved to increase chances of spontaneous abortions or congenital malformations. Similarly, nursing mothers also should not consume this drug since it is directly secreted in mother’s milk.

Due to various drug interactions, it has been prohibited for this drug to be consumed along with MAO inhibitors, or at least can not be consumed within a time period of fifteen days. The dosage of Venlafaxine increases gradually and even while discontinuation, the dosage needs to be decreased gradually. Since this drug interacts with the very important neurotransmitters found in the brain, it is important to take care of these little precautions to avoid any immediate Venlafaxine side effects. Abrupt stopping of Venlafaxine intake again can cause nausea, mood swings, changes in smelling especially towards food.

The most common Venlafaxine side effects include vomiting, headache, nervousness, sleeplessness, lethargy, and loss of appetite.
